Why should a specialized authority for artifact authentication—specifically in the fields of antiques, gemstones, and manuscript heritage—be established within the Official Experts Association of the Judiciary? And why should this authority, regardless of time or institutional fluctuations, most be reserved exclusively for certified experts with an academic degree in the conservation of historical, artistic, and cultural objects?

Since ancient times, the issue of registration in various areas of life has always been with mankind. Registration is a cultural issue and is considered a reflection of various cultural areas of mankind. Every work left by man in the past, whether it was in the form of an image or a line, reflects and illuminates a world of material and spiritual information and knowledge like an honest mirror without any pretense or imperfection. The characteristic of all registered subjects throughout history has been their "value and importance" for greater permanence and transmission to the periods ahead of them, and this transfer of value to future generations continues today. In the field of cultural heritage and the protection of historical buildings and cities, the issue of registration is very valuable and important. A noteworthy point in this field is the relevance of re-registration of values. Because we re-register the material or spiritual work registered during the creation period so that it is protected and subject to legal protection and public attention, and most importantly, in the process of sustainable development and handed down to future generations. This article, which is the result of objective observations and library and document studies, describes in an analytical-descriptive manner the nature and importance of registration and how the relationship between registration and value, conservation, and sustainable development is defined. Another goal of this article is to examine the role of registration in the protection of cultural heritage values and its place in the sustainable development process.

Historical coins, as invaluable material documents, not only hold financial significance but also serve as vivid evidence of the history, culture, art, and economy of past civilizations. In Iran, with a rich heritage spanning over 2,500 years, coins play a pivotal role in reconstructing national and cultural identity. However, the preservation and restoration of these historical treasures, particularly in private collections, face numerous challenges. Addressing these challenges requires collaboration and a sense of responsibility among collectors, conservators, and governmental institutions. Raising awareness and providing education on scientific methods of preservation and restoration, along with fostering trust between
conservators and collectors, are essential strategies for safeguarding this valuable heritage. The Ministry of Cultural Heritage, Tourism and Handicrafts (MCTH) and the Research Centre for Conservation- Restoration of Cultural Relics (RCCCR) can play a significant role by offering specialized training and necessary support. Ultimately, historical coins, as an integral part of national and cultural identity, require meticulous and responsible preservation, maintenance, and study to endure as a lasting legacy for future generations.

Soluble salts are known as serious threat for monuments and historical porous materials. The alteration mechanism related by soluble salts such as rocks is essentially a physical process based on the stress level generated by the crystallization of the salts in the pores. In recent years many ways have been developed to extract or deactivate these salts. The efficiency of every desalination system is being evaluated by the amount of extracted soluble salts and the depth of treatment in material. In fact, ionic transport is result of a consortium of energies: kinetic energy, electric energy and chemical energy. These three energies are united together to move and extraction of soluble salts in an optimum  desalination system. The electro kinetic technique is a non-destructive method to extract soluble salts based on electric migration of ions inside the material. This method is even applicable for matrixes with very fine porosity and very low hydraulic permeability. In recent years this method
has been specially considered in European countries. High amount of extracted salts and deep effect on materials have been caused to happen many researches on this topic on historical heritage and considerable results have been gained. This article is a review of background, principles and generals of this method in conservation and desalination of historical porous materials which are threatened by soluble salts alteration. Results from traditional desalination ways are compared with this method as a pioneer technique show an improvement of the quality of desalination, saving time and high efficiency of this method.

Iran, with a history spanning over 7,000 years, is considered one of the pioneers of ancient mining and metallurgy in the world. Ancient mining and metallurgy, as part of Iran's engineering and cultural heritage, play a crucial role in understanding the history of these technologies and advancing related knowledge. The study of this field contributes to the preservation of this historical and cultural legacy. Since the 1990s, organized efforts in the field of ancient mining and metallurgy have been initiated in Iran, leading to significant achievements, including the implementation of national and international projects. This research reviews key studies conducted in the field of ancient mining and metallurgy, presenting the outcomes of activities in this area. Moreover, it highlights the values embedded in the heritage of ancient mining and metallurgy, emphasizing the need to preserve this valuable legacy and register significant ancient mining and metallurgy sites as national heritage assets.

This paper analyzes the evolution of the undergraduate curriculum in historic monuments restoration in Iran, from its initial approval in 1985
to its comprehensive revision in 2022. Adopting an analytical-comparative approach, the study first explores the theoretical, historical, and practical contexts of the discipline's emergence within Iran's higher education system. It then provides a structural and content-based critique
of the earlier curriculum. The findings reveal that the original curriculum, which emphasized religious principles, cultural heritage, and basic technical training, gradually became less effective due to scientific developments, shifting field requirements, and the rise of new technologies. The 2018 revision resulted from a collaborative effort by university scholars and restoration professionals aiming to modernize the program, enhance practical training, eliminate redundant courses, add applied content, and align the curriculum with international standards. Key features of the revised curriculum include a purposeful reduction in course units, content standardization, improved integration of theoretical and practical learning, and a focus on technological competencies. Furthermore, the paper addresses the implementation challenges and resource shortages of the previous curriculum and proposes strategies to enhance the quality and efficiency of restoration education. Overall, this study emphasizes the necessity of dynamic educational planning, underlines the critical role of restoration in preserving cultural identity and strengthening social capital, and provides a framework for future curriculum reforms in the field of conservation of cultural and historical artifacts.
